Something's Fishy in the Waters of California

According to marine biologists studying sea life off the coast of California, there's something strange going on:

Scientists have discovered male fish living in Los Angeles and Orange County coastal waters that exhibit female characteristics, prompting further research into the effects of compounds in treated sewage wastewater on marine life.

Now I'm not a rocket scientist, nor a marine biologist for that matter, but I think I can solve this one for them, without spending all that well-earned research money. The problem: It's California!

'Nuff said.
